Abstract
INTRODUCTION Renal involvement of primary biliary cholangitis (PBC) usually presents as distal renal tubular acidosis. Proximal tubular (PT) dysfunctions in PBC were rarely reported with unclear clinicopathological characteristics and renal prognosis. METHODS We identified 11 cases of PBC with PT dysfunctions (PBC-PT). Their medical document, kidney pathology, and follow-up data were retrospectively reviewed and analyzed. RESULTS The 11 PBC-PT patients were mainly middle-aged (57.8 ± 5.2 years) females (81.8%). Most of them were asymptomatic PBC (7, 63.6%) with a high prevalence of elevated serum immunoglobulin M (IgM, 81.8%) and G (IgG, 54.5%) levels. In the kidney, they had a mean estimated glomerular filtration rate (eGFR) level of 46.54 ± 23.03 ml/min/1.73m2, and 81.8% of them had eGFR below 60 ml/min/1.73m2. They showed different degrees of PT dysfunctions, including hyperuricosuria, hypouricemia, normoglycemic glycosuria, generalized aminoaciduria, hyperphosphaturia, and hypophosphatemia. Their kidney pathology showed tubulointerstitial nephritis with lymphoplasmacytic infiltrates, brush border defects, and proximal tubulitis. After glucocorticoids treatment, the PT dysfunctions manifesting as hypophosphatemia, hypouricemia, and renal glycosuria all recovered, and the eGFR levels were improved from 43.24 ± 19.60 ml/min/1.73m2 to 55.02 ± 21.14 ml/min/1.73m2 (p = 0.028), accompanied by significant improvements of serum IgM levels (from 5.97 ± 4.55 g/L to 2.09 ± 1.48 g/L, p = 0.019). CONCLUSIONS The PT dysfunctions were rare in PBC patients, and glucocorticoids treatment could benefit the improvements of eGFR and tubular functions.

Abstract
BACKGROUND Pregnancy imposes significant physiological changes, including alterations in electrolyte balance and renal function. This is especially important because certain disorders might worsen and make people more susceptible to electrolyte abnormalities. One such condition is Sjogren's syndrome (SS), an autoimmune disease that can cause distal renal tubular acidosis (dRTA). This case report offers a unique perspective on the intricate physiological interplay during pregnancy, emphasizing the critical importance of recognizing and managing electrolyte abnormalities, particularly in the context of autoimmune disorders such as Sjogren's syndrome. CASE PRESENTATION We report a case of a 31-year-old pregnant Indian woman at 24 weeks gestation presenting with fever, gastrointestinal symptoms, and progressive quadriparesis followed by altered sensorium. Severe hypokalaemia and respiratory acidosis necessitated immediate intubation and ventilatory support. Investigations revealed hypokalaemia, normal anion gap metabolic acidosis, and positive autoimmune markers for SS. Concurrently, she tested positive for IgM Leptospira. Management involved aggressive correction of electrolyte imbalances and addressing the underlying SS and leptospirosis. CONCLUSION This case underscores that prompt recognition and management are paramount to prevent life-threatening complications in pregnant patients with autoimmune disease. This report sheds light on the unique challenge of managing hypokalaemic quadriparesis in the context of Sjogren's syndrome during pregnancy.

Abstract
Renal tubular acidosis type 1 (RTA-1) is a disorder where kidneys are unable to acidify urine, which ultimately results in normal anion gap metabolic acidosis. Its initial presentations and subsequent clinical manifestations can vary depending on the underlying cause and severity of the disease. We report a case of a 26-year-old female with a recent history of complicated pregnancy. She presented to a tertiary care hospital with quadriplegia and shortness of breath and required ventilator support. The extensive workup revealed that the patient had RTA-1 in association with Sjögren's syndrome. There are only a few cases of RTA-1 reported where the diagnosis was made during the pregnancy. By reporting this case of RTA-1 with rare initial clinical presentation and a recent complicated pregnancy, we propose that further research studies should be carried out in this area to explore a possible statistically significant association between pregnancy (and its complications) and RTA-1 exacerbation.

[PMID: 36324184 DOI: 10.1111/1756-185x.14483] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 09/03/2022] [Accepted: 10/10/2022] [Indexed: 11/06/2022]
Abstract
AIM To describe the clinical and laboratory features of Sjögren's syndrome (SS) with renal tubular acidosis (RTA) from published literature. METHODS A systematic search of indexed publications in all languages till December 2021 identified cases of SS with RTA (SS-RTA) and were included if either antibody (anti-SSA/anti-SSB) or salivary gland histopathology were positive. RESULTS There were 440 cases of SS-RTA (63.9% from Asia, 95.5% women). The median (range) age was 37 (6-78) years. Only 7.7% had a previous diagnosis of SS. Oral or ocular sicca symptoms were present in 63.7%. Positive ocular tests, oral tests, anti-SSA, anti-SSB and salivary gland histopathology were reported in 256/331 (77.3%), 123/128 (96%), 382/407 (93.9%), 298/379 (78.6%), and 246/268 (91.8%), respectively. Hypokalemic paralysis (HP) was the presenting feature in 63.6%; 25% had multiple episodes of HP and 8.4% had respiratory paralysis. Type 1, type 2, combined type 1 & 2, and type 4 RTA was seen in 388, 8, 38, and 3 patients, respectively. Proximal dysfunction and RTA complications were infrequently evaluated. Fanconi syndrome, nephrogenic diabetes insipidus, proteinuria, and low estimated glomerular filtration rate were found in 45, 21, 178, and 157, respectively. Nephrocalcinosis, renal stones, and osteomalacia were reported in 92, 79, and 72, respectively. Tubulointerstitial nephritis was found in 142 out of 152 renal biopsies. CONCLUSION SS-RTA is an early manifestation of SS characterized by younger age and subclinical sicca symptoms. Although evaluated less frequently, oral sicca signs and salivary gland biopsy have a high positive yield. HP is the most common presentation. RTA is mostly distal; proximal dysfunction and complications were infrequently assessed.

Recommendations for evaluation and diagnosis of extra-glandular manifestations of primary sjogren syndrome: results of an epidemiologic systematic review/meta-analysis and a consensus guideline from the Brazilian Society of Rheumatology (articular, pulmonary and renal). Adv Rheumatol 2022; 62:18. [PMID: 35650656 DOI: 10.1186/s42358-022-00248-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 05/15/2022] [Indexed: 11/10/2022] Open
Abstract
Sjogren's Syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs, associated with sicca syndrome but also with systemic involvement with varying degrees of severity. Despite their importance, these systemic manifestations are not routinely evaluated and there is no homogenous approach to their diagnosis or evaluation. To close this gap, a panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis on the identification of epidemiologic and clinical features of these manifestations and made recommendations based on the findings. Agreement between the experts was achieved using the Delphi method. The first part of this guideline summarizes the most important topics, and 11 recommendations are provided for the articular, pulmonary, and renal care of SS patients.

Abstract
BACKGROUND Autoimmune polyendocrine syndrome type 1 (APS1) is a hereditary disease caused by mutations in the AIRE gene with both endocrine and non-endocrine organ involvement. The existing data from China are limited, and this study aims to describe the phenotypes and genetic characterization in Chinese APS1 patients. In this single-center, retrospective, observational study, comprehensive endocrine and extra-endocrine manifestations were collected, and genetic analysis in AIRE was conducted in patients with APS1 between the years of 1984 and 2018 at Peking Union Medical College Hospital. RESULTS In total, 13 patients from 12 unrelated families were enrolled, seven of whom were female, with hypoparathyroidism, chronic mucocutaneous candidiasis, and Addison's disease being the most frequently observed manifestations. Up to 84.7% presented with two or three of the above-mentioned manifestations, and nearly 4.9 ± 1.8 components presented in patients aged 21.2 ± 7.9 years old. Several less common phenotypes, such as myeloproliferative disease, pure red cell aplasia, renal tubular acidosis, asplenia, autoimmune hepatitis, and ankylosing spondylitis, were also observed in patients. Altogether, seven different AIRE mutations were found in six patients, four of which (K161fs, G208V, A246fs, and L308F) had not been previously reported in patients with APS1. CONCLUSION We have provided a comprehensive profile of Chinese patients with APS1, with less commonly observed features being observed in addition to more regularly seen manifestations. Additionally, different AIRE mutations that were observed have expanded the genetic spectrum, which will help with future understanding of the molecular pathogenesis of APS1.

Abstract
The immune renal tubular diseases are known since five decades, but their prevalence remains to be defined. They are caused by humoral and cellular effectors of innate and adaptative immunities on several targets of the renal tubule: protein channels, co or counter transporters, luminal or cytosolic enzymes, tight junctions. Genetic or epigenetic variations are also involved. Clinical manifestations are various and make the diagnosis difficult. They can precede the causal affection and they worsen the prognosis. The classical model consists in hypokalemic tubular distal acidosis observed in Sjögren's syndrome which illustrates the auto-immune epithelitis concept. Cellular immunity can act through other ways, like tertiary lymphoid neogenesis in systemic lupus. Humoral immunity through autoantibodies targets several membrane, cytosolic or nuclear proteins, causing specific tubular dysfonctions. It is also implied in the epithelial-mesenchymal transition of tubular cells. Innate immunity through cytokines may be involved. Treatment consists in electrolytic disorders correction and immunosupppressive medication: the choice should be guided at best by physiopathology.

Abstract
PURPOSE OF THE STUDY Reversible proximal tubular dysfunction associated with distal renal tubular acidosis (dRTA) mimics type 3 RTA, a condition classically associated with features of both proximal RTA (pRTA) and dRTA. Proximal tubulopathy has been reported in children with primary dRTA, but the data in adults are lacking. STUDY DESIGN In this hospital record-based retrospective study, data from 66 consecutive cases of RTA, between January 2016 to December 2018, were retrieved and analyzed. RESULTS Mean age of the study population was 25.3 years (range: 3 months to 73 years). Six (9.1%) of them had pRTA, 58 (87.9%) had dRTA, 1 (1.5%) had type 3 RTA, and the remaining 1 (1.5%) had type 4 RTA. Ten patients (17.2%) with dRTA and 3 patients of pRTA (50%) had underlying secondary etiologies. Data on proximal tubular dysfunction were available for 30 patients with dRTA, of whom 1 had isolated dRTA, and the rest 29 patients had accompanying completely reversible proximal tubular dysfunction. Among the 10 cases of secondary dRTA, 6 were not evaluated for proximal tubular dysfunction. Of the remaining 4, 3 had reversible form of proximal tubular abnormality. Fifty-two patients with dRTA came from a population, indigenous to the "Rarh" region of India. CONCLUSIONS Proximal tubular dysfunction often accompanies dRTA; 75% of the children with primary dRTA, at least 29% of adults with primary dRTA, and at least 30% of adults with secondary dRTA manifest such completely reversible form of proximal tubulopathy. "Rarh' region of India probably is a hotspot for endemic dRTA.

Abstract
Background and aims: Monoclonal immunoglobulin light chain associated Fanconi syndrome (LC-FS) is a rare disease that involves proximal tubules. As most of the reported cases came from western countries, we aimed to analyze the clinicopathological characteristics of Asian LC-FS and its treatment responses to chemotherapy. Methods: A total of 26 LC-FS patients in a single-center were retrospectively studied. Results: At diagnosis, the mean age of the 26 Asian LC-FS patients was 54.7 ± 14.7 years, with females accounting for 57.7%. They presented with different degrees of proximal tubular dysfunctions with normoglycemic glycosuria (88.0%), hyperphosphaturia (84.2%) and aminoaciduria (84.0%) as the most common features. The mean estimated glomerular filtration rate (eGFR) was (68.0 ± 26.4) ml/min per 1.73 m2. After chemotherapy, renal response was achieved in 58.3% cases, which was accompanied by hematological response, and tubular response was acquired in 66.7% cases. During 3 years of follow-up, the eGFR levels significantly decreased in the monoclonal gammopathy of renal significance patients, few of whom (21.4%) had received chemotherapy. Conclusion: Asian LC-FS patients had mild renal function disorder. The chemotherapy could improve both renal and tubular functions, which may be related to the hematological response.

Abstract
BACKGROUND Renal Fanconi syndrome (FS) is rare in primary Sjӧgren's syndrome (pSS). We aimed to describe the clinicopathological characteristics of pSS associated FS (pSS-FS) and its responses to treatment. METHODS We reported 25 cases of pSS-FS patients and retrospectively reviewed their clinical records, kidney pathology and follow-up data. RESULTS The 25 pSS-FS patients were mainly female (92.0%) and the mean age at diagnosis was 43.6±11.3 years. They showed different degrees of proximal tubular dysfunctions and eGFR decline (60.9±32.3 ml/min/1.73m2). Kidney pathology of pSS-FS patients showed tubulo-interstitial nephritis with defective brush border and lymphoplasmacytic infiltrates. After glucocorticoid treatment, the eGFR levels were significantly improved from 48.3±20.6 ml/min/1.73m2 to 55.0±19.9 ml/min/1.73m2 (P = 0.012) at the third month of follow-up. They also acquired good tubular (88.2%) and immunological (90.0%) responses. pSS-FS patients with young-onset pSS presented with a higher prevalence of positive anti-SSB antibody and hypocomplementemia, more severe hypokalemia, and better eGFR levels. CONCLUSIONS In pSS-FS patients, use of glucocorticoids could improve eGFR and tubular functions.

Abstract
Renal Fanconi syndrome (RFS) is characterised by generalised dysfunction of the proximal renal tubules, resulting in excessive urinary loss of solutes, most notably bicarbonate, and type II (proximal) renal tubular acidosis. It is a rare condition, and literature around its management through pregnancy is limited. We present the management of a 37-year-old woman with RFS secondary to the HNF4A p.R63W mutation, through her third pregnancy. She presented at 28 + 5 weeks with dehydration, low serum bicarbonate, and profound metabolic acidosis. Daily infusions of sodium bicarbonate were necessary, and the requirements increased throughout the pregnancy. She also demonstrated both fasting hypoglycaemia and episodes of postprandial hyperglycaemia which required complex management. Due to concerns around fetal health, an elective caesarean section was performed at 34 weeks, delivering a healthy baby girl. This case highlights the potential complexity of pregnancy in patients with RFS and the need for a multidisciplinary approach to its management.

Abstract
Primary Sjögren's syndrome (pSS) primarily involves exocrine glands, and renal tubular acidosis (RTA) is seen in one-third of the cases. RTA with hypokalemic paralysis as a presenting feature of pSS is described in few case reports in literature. We report 13 cases who presented as hypokalemic paralysis, and on evaluation were diagnosed to be pSS, as per the diagnostic criteria laid by the Sjögren's International Collaborative Clinical Alliance (2012). All patients were female, with a mean age at presentation being 33.1 ± 8.22 years (range, 25–48 years). Eleven patients had a complete distal RTA and two patients had incomplete distal RTA at the time of presentation. 62% (8/13) of patients had no signs and symptoms of exocrine gland involvement. All the cases were managed with oral alkali therapy, and six patients received additional immunomodulating agents. No improvement in renal tubular dysfunction (in the form of a reduction in the alkali dose) after immunomodulating therapy was observed over a mean follow-up of 2.8 years. Renal tubular dysfunction can be the presenting manifestation of pSS. It is important to consider the possible presence of this disorder in adults with otherwise unexplained distal RTA or hypokalemia.

Abstract
Hypokalemic paralysis is an important and reversible cause of acute flaccid paralysis. The treating physician faces unique diagnostic and therapeutic challenges. We did a prospective study and included all patients with acute flaccid weakness and documented serum potassium of <3.5 mEq/L during the period between January 2009 and August 2015. We studied the incidence, etiology, clinical profile, and acid-base disturbances in patients presenting with hypokalemic paralysis and analyzed the significance of periodic and non-periodic forms of hypokalemic paralysis on patient's outcome. Two hundred and six patients were studied with a mean follow-up of 3.6 ± 1.2 years. Mean age was 37.61 ± 2.2 years (range 18-50 years). Males were predominant (M:F ratio 2.1:1). The nonperiodic form of hypokalemic paralysis was the most common (61%). Eighty-one (39%) patients had metabolic acidosis, 78 (38%) had normal acid-base status, and 47 (23%) patients had metabolic alkalosis. The most common secondary cause was distal renal tubular acidosis (RTA) (n = 75, 36%), followed by Gitelman syndrome (n = 39, 18%), thyrotoxic paralysis (n = 8, 4%), hyperaldosteronism (n = 7, 3%), and proximal RTA (n = 6, 4%). Patients with non-periodic paralysis had more urinary loss (40.1 vs. 12.2 mmol, P = 0.04), more requirement of potassium replacement (120 vs. 48 mmol, P = 0.05), and longer recovery time of weakness (48.1 vs. 16.5 h, P = 0.05) than patients with periodic paralysis. Non-periodic form of hypokalemic paralysis was the most common variant in our study. Patients with periodic paralysis had significant incidence of rebound hyperkalemia.

Abstract
BACKGROUND Sjögren's syndrome is an autoimmune disorder caused by the infiltration of monocytes in epithelial glandular and extra-glandular tissues. Hallmark presentations include mouth and eye dryness. Although renal involvement is uncommon in primary Sjögren's syndrome (pSS), patients may experience renal tubular acidosis type I (RTA I), tubulointerstitial nephritis, diabetes insipidus (DI), nephrolithiasis, and Fanconi syndrome. However, it is atypical to see more than 1 of these manifestations in a single patient. CASE REPORT We present the case of a 24-year-old woman with polyuria and polydipsia, who was initially diagnosed with nephrogenic diabetes insipidus. She also had chronic hypokalemia and nephrolithiasis. Based on clinical presentation and work up, she was diagnosed with pSS and treated accordingly. CONCLUSIONS This was a pSS patient with tubulointerstitial nephritis, diabetes insipidus, renal tubular acidosis, hypokalemia, and nephrolithiasis, who was receiving symptomatic treatment for diabetes insipidus. Diagnosis and treatment of pSS led to significant improvement in systemic and renal presentations of the patient. pSS should be considered as one of the differential diagnoses in patients with diabetes insipidus and renal tubular acidosis.

Abstract
Interstitial nephritis is responsible for about 12 % of end-stage renal disease in Germany. It comprises an etiologically heterogenous group of inflammatory renal disorders which primarily affect the renal interstitium and tubuli. Drugs, predominantly antibiotics, nonsteroidal anti-inflammatory drugs and proton pump inhibitors are causative in the majority of cases. Rheumatic diseases frequently affect the kidneys, either the glomeruli or the interstitial tissues. Inflammatory interstitial processes can be accompanied by complex functional tubular disorders. This review gives an overview about clinical and laboratory findings of interstitial nephritis in the context of rheumatic diseases. Sarcoidosis, tubulointerstitial nephritis and uveitis (TINU) syndrome, primary Sjogren's syndrome, and IgG4-related disease often show an interstitial nephritis when the kidneys are affected. Other diseases, such as systemic lupus erythematosus, systemic sclerosis, drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, and granulomatosis with polyangiitis are more rarely associated with predominant interstitial nephritis. Glucocorticoids are the mainstay of therapy for most cases; in refractory cases or when side effects occur, second-line immunosuppressants such as mycophenolate mofetil, azathioprine and others, rarely biologics, can be used.

Abstract
The Nephrology Quiz and Questionnaire remains an extremely popular session for attendees of the Annual Kidney Week Meeting of the American Society of Nephrology. Once again, in 2014 the conference hall was overflowing with audience members and eager quiz participants. Topics covered by the expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases from each of these categories along with single-best-answer questions were prepared and submitted by the panel of experts. Before the meeting, program directors of United States nephrology training programs and nephrology fellows answered the questions using an Internet-based questionnaire. During the live session, members of the audience tested their knowledge and judgment on a series of case-oriented questions prepared and discussed by the experts. They compared their answers in real time using audience response devices with the answers of the nephrology fellows and training program directors. The correct and incorrect answers were then discussed after the audience responses and the results of the questionnaire were displayed. As always, the audience, lecturers, and moderators enjoyed this educational session. This article recapitulates the acid-base and electrolyte disorders portion of the session and reproduces its educational value for the readers of the Clinical Journal of the American Society of Nephrology. Enjoy the clinical cases and expert discussions.
