Abstract
Organic acidurias are a heterogeneous group of rare inherited metabolic disorders (IMDs) caused by a deficiency of an enzyme or a transport protein involved in the intermediary metabolic pathways. These enzymatic defects lead to an accumulation of organic acids in different tissues and their subsequent excretion in urine. Organic acidurias include maple syrup urine disease, propionic aciduria, methylmalonic aciduria, isovaleric aciduria, and glutaric aciduria type 1. Clinical features vary between different organic acid disorders and may present with severe complications. An increasing number of women with rare IMDs are reporting successful pregnancy outcomes. Normal pregnancy causes profound anatomical, biochemical and physiological changes. Significant changes in metabolism and nutritional requirements take place during different stages of pregnancy in IMDs. Foetal demands increase with the progression of pregnancy, representing a challenging biological stressor in patients with organic acidurias as well as catabolic states post-delivery. In this work, we present an overview of metabolic considerations for pregnancy in patients with organic acidurias.

Physical and Neurological Development of a Girl Born to a Mother with Methylmalonic Acidemia and Kidney Transplantation and Review of the Literature. CHILDREN 2021; 8:children8111013. [PMID: 34828726 PMCID: PMC8619094 DOI: 10.3390/children8111013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/08/2021] [Accepted: 11/01/2021] [Indexed: 11/24/2022]
Abstract
Background: actual literature suggests that children of methylmalonic acidemia patients are mostly healthy, but data are only partial, especially regarding long-term outcome. Therefore, our aim was to evaluate the possible long-term neurological effects of fetal exposure to high levels of methylmalonic acid in a child of a renal transplant recipient. Methods: we retrospectively evaluated the clinical and neurological records of a girl whose mother is a kidney transplant recipient affected by methylmalonic acidemia. Subsequently, we compared our results with the ones already published. Results: the girl’s weight and stature were within the normal range in the first years of life but, starting from 4 years of age, she became progressively overweight. Regarding the neurodevelopment aspects, for the first time we performed a complete and seriated neuropsychological evaluation, highlighting a mild but significant weakness in the verbal domain, with a worsening trend at three-year revaluation. Conclusions: since children of MMA patients are exposed to methylmalonic acid, the efforts of the physicians caring for these children should be directed on careful evaluation of growth, prevention of obesity and regular neurological examination together with structured neuropsychological tests to achieve a better insight in possible complications of pregnancy in patients suffering from this condition.

Abstract
Isolated methylmalonic acidaemia (MMA) and propionic acidaemia (PA) are rare inherited metabolic diseases. Six years ago, a detailed evaluation of the available evidence on diagnosis and management of these disorders has been published for the first time. The article received considerable attention, illustrating the importance of an expert panel to evaluate and compile recommendations to guide rare disease patient care. Since that time, a growing body of evidence on transplant outcomes in MMA and PA patients and use of precursor free amino acid mixtures allows for updates of the guidelines. In this article, we aim to incorporate this newly published knowledge and provide a revised version of the guidelines. The analysis was performed by a panel of multidisciplinary health care experts, who followed an updated guideline development methodology (GRADE). Hence, the full body of evidence up until autumn 2019 was re-evaluated, analysed and graded. As a result, 21 updated recommendations were compiled in a more concise paper with a focus on the existing evidence to enable well-informed decisions in the context of MMA and PA patient care.

[PMID: 25567501 PMCID: PMC4496322 DOI: 10.1007/s10545-014-9802-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2014] [Revised: 11/26/2014] [Accepted: 12/02/2014] [Indexed: 12/27/2022]
Abstract
INTRODUCTION Women with inherited metabolic disorders, including those with previously life-limiting conditions such as MMA, are reaching child-bearing age more often due to advances in early diagnosis and improved pediatric care. Information surrounding maternal and fetal complications associated with the underlying disorders remains largely unexplored. METHODS Pregnancies affected by maternal MMA were ascertained through study 04-HG-0127 "Clinical and Basic Investigations of Methylmalonic Acidemia and Related Disorders" (clinicaltrials.gov identifier: NCT00078078) and via literature review. Prenatal and delivery records in study participants were reviewed. RESULTS Seventeen pregnancies were identified in women with isolated MMA, including three abortions, one termination, and 13 completed pregnancies [three cases with cblA (four pregnancies), four cases of mut- (one cobalamin responsive, three non-responsive), five cases with unknown type of MMA]. Seventeen percent (3/17) of the pregnancies resulted in a first trimester abortion, while 38.5% (5/13) of the completed pregnancies resulted in preterm deliveries. A cesarean delivery rate of 53.8% (7/13) was noted among the cohort. Fetal distress or nonreassuring fetal status was the indication for 57% (4/7) cesarean deliveries. One patient was reported to have metabolic crisis as well as episodes of mild hyperammonemia. Malformations or adverse outcomes in the progeny were not observed. CONCLUSION Although there have been a small number of pregnancies identified in women with MMA, the cumulative results suggest that the majority of pregnancies can be complicated by cesarean delivery and increased risk of prematurity. A pregnancy registry could clarify perinatal complications and define management approaches needed to ensure optimal maternal and fetal outcomes in this growing patient population.

Abstract
A 27-year-old woman with vitamin B12 responsive form of methylmalonic acidaemia (MMA) was pregnant with her first child. Treatment was unaltered during pregnancy: a low-protein diet and supplements. Her pregnancy was uncomplicated. She had a spontaneous delivery of a healthy girl with no MMA. The postpartum period was uneventful. MMA is a rare autosomal recessive metabolic disorder caused by a deficiency of methylmalonyl coenzyme A mutase or its vitamin B12-dependent cofactor, leading to a toxic accumulation of methylmalonyl acid in plasma and urine. Clinical presentation involves otherwise unexplained deterioration and neurological dysfunction, recurrent vomiting, dehydration, lethargy, respiratory distress and muscular hypotonia. Long-term sequelae are neurological problems, renal failure, pancreatitis and cardiomyopathy. This is the 11th reported case of pregnancy in a woman with MMA.

Pregnancy in a methylmalonic acidemia patient with kidney transplantation: a case report. Am J Transplant 2013; 13:1918-22.

Abstract
Presently pregnancy is no more exceptional in women with metabolic diseases. However, it still poses significant medical problems both before and after childbirth. The challenge is even greater if the mother has undergone organ transplantation, because of her metabolic disease. We report on a case of pregnancy in a patient 29-year-old with methylmalonic acidemia cblA type (OMIM 251100) who received a renal transplantation at the age of 17 for end-stage renal disease (ESRD) caused by her primary disease. During pregnancy neither metabolic crises nor renal function changes were observed in the mother, with the only exception of a mild increase of her systemic blood pressure. To the fetus pregnancy was uneventful and during the first 30 months after birth the baby's neuropsychomotor development was normal and there were no episodes of metabolic derangement. This is evidence that methylmalonicacidemia cblA, even when treated with renal transplantation for inherent ESRD, is no contraindication to pregnancy. It is even possible that a functioning transplanted kidney contributes to improve metabolic parameters.

Abstract
OBJECTIVE To report the successful pregnancy of a woman with methylmalonic acidemia and hyperhomocysteinemia, cblC type [cobalamin C (cblC) deficiency] (MIM 277400). METHOD Retrospective chart review. RESULTS A 24-year-old woman presented at 14 weeks gestation with nausea, self-restricted protein diet, and weight loss. She had a past history of asymptomatic methylmalonic acidemia but had been lost to follow-up since the age of 15 years. Biochemical evaluation revealed combined methylmalonic acidemia and hyperhomocysteinemia. Complementation analysis confirmed cblC deficiency. One copy of the most common mutations in the MMACHC gene, c.271dupA, was identified. The women was treated from 15 weeks of gestation with a low protein diet (64 g/day) (1.1 g /kg of weight/day), L-carnitine (1 g per os 3 times daily to 3 g per os 3 times daily in the third trimester), aspirin (salicylic acid) 80 mg per day, folic acid 5 mg per day, and hydroxocobalamin 1 mg intramuscular every week to two times per week in the third trimester. The pregnancy was uneventful and the delivery at term. The newborn was healthy at delivery and at follow-up. CONCLUSION We report on the successful outcome of pregnancy in a treated woman with cblC disease. The pregnancy was uneventful for both fetus and mother with the delivery of a term healthy boy. There is a need for an international registry on the management and outcomes of pregnancy in women with inborn errors of metabolism.
